What are these and how do I remove them?

and what in the heck is this little guy?
The one on the front is your Purge valve for your emissions to vent fumes out of the gas tank. If I recall, there shuold be spring loaded C-Clip (white?) the if you push it up, the connector will slip off the port of the intake. If youd don't need it for your car or state emission, you can plug the port or use it. I use the port to pull vacuum from my stock Charcoal Canister to vent the fumes from my gas tank.
